Abstract
The utility model discloses a combined hammer, which comprises more than two kinds of hammers in a column hammer, a middle hammer or a flat hammer, wherein the column hammer, the middle hammer and the flat hammer all comprise a hammer body, a hanging shaft and a hanging lug, the hammer body is divided into a multi-stage combined mode, an integrated casting mode or an outsourcing inner casting mode, which is that the hammer body uses metal materials to make an external mold, and the inner portion of the mold is filled or cast by materials with large proportion. The depth can be effectively reinforced and increased 1-2 times through using the combined hammer under the situation that the lifting capacity and the lifting height of a crane are kept in a certain, which is that the tamping energy is same, simultaneously the reinforced foundation bearing capacity can be increased 0.5-1 time, and the foundation settlement amount and the settlement difference can be effectively reduced. The combined hammer further has the advantages of simple structure, easy operation, convenient use and more obvious effects, and is a simplest device in deep soft soil layer foundation dynamic compaction reinforcement treatment construction at home at present.
Description
Technical field
The utility model relates to the building lot treatment facility, especially relates to a kind of combination hammer that is used to improve the science of foundation strength and effective reinforcement depth.
Background technology
In the Foundation Treatment of construction work, run into backfill and loose earth filling is thicker or the low designing requirement that can not satisfy upper load, dynamic load of intensity through regular meeting; if when adopting dynamic compaction since the condition that can not infinitely strengthen by tamping energy limit; the effective reinforcement depth of foundation soil can not meet design requirement; there is the phenomenon that the surface is closely knit, lower floor is loose; can produce spongy soil when soil body water content is excessive, its consolidation effect is bad.If when adopting other composite foundation technology, cause poor effect or cost too high because of reinforcing inter-pile soil simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, processing ease, easy to use, effect more significantly to make up hammer, it not only can increase effective reinforcement depth widely, super dark soft soil horizon is carried out compacted, displacement, but simultaneously centering layer soil body and the shallow-layer soil body carry out compacted, displacement.
The purpose of this utility model is achieved in that a kind of combination hammer, feature is made up of the two or more hammers in post hammer, middle hammer or the enlarging hammer, post hammer, middle hammer and enlarging hammer are formed by hammer body, hanging axis, hanger, and that hammer body divides is multi-section combined, integral cast formula or outsourcing inner casting, be that hammer body adopts metal material to make external mold, fill or casting with the bigger material of proportion in the mould.
That the hammer body of post hammer is shaped as is cylindrical, a kind of in square column type, wedge cylindricality, polygon cylindricality or the sliding weight of steelyard shape, and middle hammer, enlarging hammer hammer body shape are a kind of in circle, square, hexagon, polygon or the sliding weight of steelyard shape.
Post hammer ratio of height to diameter is greater than 1, and static pressure value and dynamic pressure equivalent are very big, is used for the soil body is carried out compacted, the displacement of deep layer.Middle hammer ratio of height to diameter about 0.5, static pressure value and dynamic pressure equivalent are general, are used for, displacement compacted to soil body middle level.Enlarging hammer ratio of height to diameter about 0.25, static pressure value and dynamic pressure equivalent minimum are used for the top layer compacting, the whole construction that links up, hammering overlap joint.
The diameter or the length of side of post hammer are 0.6～1.6m, high 1.5～5m, and weight 4～40T, the diameter of middle hammer or the length of side are 1.2～2.4m, high 0.5～1.5m, weight 4～40T, enlarging hammer are that the diameter or the length of side are 1.8～3.2m, high 0.3～1.5m, weight 4～40T.
The utility model is made up of the two or more hammer bodies in post hammer, middle hammer or the enlarging hammer.During construction, the equivalent of lifting dynamic pressure earlier is big, the penetration power of the soil body is strengthened and to the post hammer of the compacted displacement of deep foundation soil, back lifting dynamic pressure equivalent is general, in to the compacting of pier body to pier between in layer soil body carry out compacted strong middle hammer, it is little, strong but easily to the enlarging hammer of the compacted displacement of shallow layer foundation soil to the penetration power of the soil body that the dynamic pressure equivalent is hung in recurrence.
During construction, utilize crane gear and automatic decoupling device that the post hammer is sling to predetermined altitude free-falling again, carry out repeated stock compacting formation tamping pit, then original soil or displacement material are filled and led up, carry out the compacted displacement of deep layer being reinforced the soil body.Hammer carries out the compacted displacement in middle level by last method construction in using again, carries out the top layer compacting by enlarging hammer then, to reach foundation soil is carried out the reinforcing of layering clearly.Ram, backfill, ram again through the same point position of multipass repeatedly coherent, form up big and down small single vertical displacement pier or strengthen body, form by N pier body with by soil between compacted pier and whole full rammer compound action and make up hammer method composite foundation.
Under the lifting capacity of loop wheel machine and sling height keep certain situation, when being equal tamping energy, use the combination hammer can make effective reinforcement depth improve 1～2 times, can make the bearing capacity of foundation soil of reinforcing improve 0.5～1 times simultaneously, and can effectively reduce settlement of foundation and settlement difference.That the utility model also has is simple in structure, the more tangible advantage of processing ease, easy to use, effect, and the utility model is at present domestic to the easiest equipment in the construction of deep soft soil foundation dynamic consolidation consolidation process.
